Small bowel transplant (SBT) is a surgical procedure that may be used in patients with pathology resulting in severe intestinal failure resistant to conventional forms of surgical and nonsurgical treatment. Intestinal failure is defined as the failure of enterocytes to absorb sufficient macronutrients, water, and/or electrolytes to sustain homeostasis and/or promote growth. With the advancement of surgical techniques and advancements in perioperative transplant management, SBT has become an increasingly common treatment for intestinal failure, with survival rates for SBT comparable to those for other solid organ transplants.
This review provides background on SBT, its variations, and the associated preoperative and postoperative imaging studies with regard to surgical planning and anticipated complications.
With the increasing use of SBT, radiologists will be expected to be familiar with the diagnostic studies and available endovascular interventions associated with this procedure.
小肠移植（SBT）是一种外科手术，可能用于治疗因严重肠道衰竭而对传统手术和非手术治疗方法产生抗药性的患者。肠道衰竭被定义为肠细胞吸收足够的宏量营养素、水和/或电解质以维持体内平衡和/或促进生长的能力丧失。随着外科技术的进步和围手术期移植管理的进步，SBT 已成为治疗肠道衰竭的一种越来越常见的方法，SBT 的存活率与其他实体器官移植相当。
本综述提供了 SBT 的背景信息，包括其变体以及与手术计划和预期并发症相关的术前和术后影像学研究。
随着 SBT 的使用越来越多，放射科医生预计将熟悉与该手术相关的诊断研究和可获得的血管内介入治疗。
